Chemical Structure
Description
CATO supplies 6-Amino-3-(4-chlorophenyl)-1-phenyl-1H-pyrazolo[3,4-b]pyridine-4,5-dicarbonitrile (CAS 84637-33-2), a certified reference material (molecular formula C20H11ClN6, MW 370.79 g/mol) for analytical method development and quality control.
The molecular framework of 6-Amino-3-(4-chlorophenyl)-1-phenyl-1H-pyrazolo[3,4-b]pyridine-4,5-dicarbonitrile (C20H11ClN6) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
